Hi,
Thanks for all of the suggestions. My original wording did contain information about the doctor’s evaluation. I thought it made the question unnecessarily wordy so I deleted it before posting. The doctor has ordered another blood draw in 30 days to see if this is just an anomaly.
Anyway, @MaudeD , @OreoCookie and others, all of the other measurements came back within whatever the acceptable range is, often right in the middle. Potassium is the only measurement that was outside its range and that only by 0.1.
I finally took @ambermalika 's advice not to diet on the bike and have been consistently nailing all of the workouts with this one change. I’ll stop the drink for 30 days until the next blood draw. If the high reading persists, I’ll try some of the recommendations for making my own mix. As a cyclist, I can be guilty of overthinking things.
